Title: E-racer Spar for sale $750
Post by: Marc Oppelt on January 17, 2014, 10:33:36 PM
E-racer spar, constructed as per plans but with two modifications:
1. Bottom of the spar is straight like a Long-EZ / Cozy 3 spar, with no dropped center section to accommodate the driveshaft arrangement that was part of the original V8 E-racer's powertrain. If you plan to hang an aircraft engine on the firewall (like most do) then why do you need that dropped section anyway?
2. Spar is entirely constructed with Divinycell foam core (not that Urethane crap), and Pro-Set epoxy resin.
This spar could also be used for a Long-EZ, if you build wings to match. That means building wings using the E-racer layup schedule (25% thicker spar caps & (IIRC) 1 more full length ply in the shear web). This is what gives the E-racer it's 300 mph VNE vs the Long-EZ's 220 mph. This would also require strake skins that are 2" longer as this spar is 2" narrower than Long-EZ...and would give some added fuel capacity in the tanks
